GLAZINGr-BAR 0F ROOFS AND THE LIKE.

Specification of Letters Patent.

Patented Jan. 8, 1918.

Application filed June 1, 1917. Serial No. 172,333.

To all whom it may concern:

Be it known that I, RALPH WALTER Horn, a subject of the King of Great Britain and Ireland, and residing at Lionel street, Birmingham, in the county of Warwick, England, have invented certain new and useful Improvements Relating to the Glazing-Bars of Roots and the like, of which the following is a specification. I

This invention relates to stops which are secured to the glazing bars of roofs and the like for retaining the glass in position and are known as glass stops.

Such glazing bars'have been previously provided at the bottom end with a special shoe which has the double object of securing the bars to the purlin and also holding the glass in position, with-out requiring any cutting away or disturbance of the rust-preventing coating.

In some cases, however, the overhang oi the glass from the purlin is so great that such a shoe cannot be used, and it is then usual to secure the bars to the purlin by means of plates and to use in addition glass stops at the end of the bars to prevent the glass from sliding down. For securing these glass stops to the bars the usual methods previously employed are to fiX-the stops by means of set screws into the underside of the bar, or by using a cotter pin which is put through a hole in the stalk of the bar. Both these methods have proved to be unsatisfactory, inasmuch as the holes made in the lead sheath provide accessfor moisture to the steel core and the fixing screws are necessarily so small that they are a source of weakness.

The object of the present invention is to provide an improved construction of glass stop device to obviate the above disadvantages.

The invention consists in a modified construction of glass stop device, comprising a central portion against which the glass rests, a screwed tail piece which passes through a hole in'an extension of the glazing bar flange for clamping thereto and one or more fingers projecting above the glass.

In the accompanying drawings Figure 1 is an end elevation of the stop as attached to the end of a glazing bar.

Fig. 2 is a side elevation of the stop with Copies of this patent may be obtained for a portion of the glazing bar, showing the relative position of stop.

Fig. 3 is a plan of Fig. 2.

In carrying this invention into effect in one form, I provide the end of the glazing bar a with a bracket stop of the form shown, comprising a bifurcated L-shaped bracket 6 the web portion a of which has formed thereon a boss or projection (Z on. one side for strengthening the bracket, the said boss being provided with a projecting pin 6 the end of which is screw threaded, by which means it can be secured by a screw nut f in a hole provided in an extension of the horizontal member of the T-shaped glazing bar a, the vertical member of which has been cut back as shown to receive the hole. On the opposite side of the web 0 I provide two 1 nger-like projections g, which project above and over the glass lying between the glazing bars, which fingers effectually prevent the glass sliding down or being lifted by wind pressure.

The glazing bar it of T-shapef for example is prepared by cutting back the stalk or vertical member and drilling a suitable hole for the reception of the screwed pin 0 or" the L- shaped bracket 7) in the remaining flange part or horizontal member of the glazing bar; the bar is then subjected to a rust-proof process and subsequently wholly covered with a lead sheath of the usual kind, whereby access of moisture to the core is obviated.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is A stop or bracket for the glazing bars of roofs and the like, comprising a central web portion against one side of which the glass abuts, a boss formed on the opposite side of he web having an extension pin formed thereon with its lower end screw threaded for the purpose of being secured by a nut to the glazing bar, and providing at the upper part of the central web a bifurcated portion consisting of finger-like projections for extending over the glass when in position, substantially as shown and described.

In testimony whereof I have aliiXed my signature.

RALPH WALTER HQPE.
